I’ve been traveling along the coast of South Carolina this week, and on Thursday, I found myself in the historic town of Conway, South Carolina. I parked downtown and strolled into the past via Papa’s General Store, a small local store with a lot of merchandise––and a lot of charm.

While browsing a display of antiques, I happened to notice a vintage radio perched on a high shelf. Here’s what caught my eye:

I asked, was the radio was for sale? And, indeed, it was. One of the sales clerks pulled it from the shelf, dusted off the top, and read the price: $74. I noted that it was a West German Telefunken receiver.  I asked the clerk, Chris,  if it worked, and he confirmed that it did; it belonged to his uncle, who had clearly taken very good care of it.

Chris allowed me to plug it in, turn it on, and tune in a couple of local stations…The Telefunken produced beautiful audio without even the slightest hint of a hum. Chris was pleased that I appreciated the radio, and sincerely wanted me to take it home, so he lowered the price a bit further.  I agreed, and purchased it without hesitation. Just couldn’t help it…

Chris behind the counter with his uncle’s classic Telefunken.

The Telefunken Superheterodyn Caprice 5451W covers the AM/mediumwave band and FM. It’s a tube radio produced in the early 1960s in West Germany, and is now the only tube-based radio I own that covers the FM band.

Of course, I was very eager to get the Telefunken on the air, so that afternoon I headed to our balcony overlooking the Atlantic, tuned around a bit on the mediumwave band…and was simply amazed at all it could receive.  I picked up my smart phone, and with it made a very short recording of the Cuban station, Radio Reloj, on 820 kHz:

My smart phone’s microphone doesn’t begin to do the Telefunken’s rich audio justice, but you can clearly hear Radio Reloj’s ticks and “RR” in Morse Code at the top of the minute (indeed, if you’re listening with headphones, you may also hear crashing waves in the background). Something nearby generated a lot of RFI right on frequency, too , but the rest of the broadcast band had a surprisingly low noise floor.

I also spent some time with the Telefunken on the FM broadcast band; with a simple wire antenna, this worked wonders.

In my humble op, the audio the Telefunken produces is simply beautiful.  And so, I’ve got to add, is this vintage radio. See for yourself.

It seems that Tecsun has a new large portable in line.

Someone posted a photo of a new Tecsun product catalogue which shows a new model S8800.

The Tecsun BCL-3000 for comparison.

Apparently it uses the housing of BCL3000 [see above] and is multiple conversion (so a PL880 inside?), DSP based with separate LSB/USB and 10Hz minimum tuning step, and comes with a remote control (for direct frequency input?). Two 18650 batteries are used.

[Here’s a] link to the post in Tecsun’s web forum:

http://bbs.tecsun.com.cn/0002.asp?open=730351

Many thanks for sharing this find, OWL! This is a very curious development from Tecsun.

I can imagine why Tecsun is re-using the BCL-3000 (a.k.a. Grundig S350DL) body–not only is it roomy inside, but it’s proven to be a popular large portable form factor over the years. Of course, since this is an existing chassis design, design/development costs will be minimal.  If Tecsun is including a remote, I’m sure OWL is correct: it’ll aid with direct frequency entry. The S-8800 will be the first portable shortwave radio with remote control I’ve seen in many years.

If audio is anything like its predecessors, I would expect rich fidelity from the built-in speaker. In terms of performance, though? This is a completely different receiver than the single-conversion BCL-3000, so only time will tell.

Many thanks, Andi!  These photos are excellent and certainly give us more insight into the new Degen DE1103 design.

I’m very curious how this new DE1103 compares with other DSP portables on the market.

After learning about the new Tecsun S-8800, yesterday, I contacted Anna at Anon-Co and asked for any information regarding specs and availability.  Anna replied:

“Regarding the S-8800, there is no information available of when this will be actually launched. I think that the absolute earliest could be some time in January, but I expect that it will be after Chinese New Year. To be honest, it is very difficult to say at this moment. There isn’t much information available about it yet.

Supposedly it is pretty much the same [chassis design] as the existing BCL-3000, but it will be a PLL radio with DSP IC. It should have SSB features, but other details (like SYNC) I’m not aware of at this moment. I’m hoping to hear more about this soon.

Anna will contact me as soon as she has more info about the S-8800 features and availability.

Regarding the C.Crane CC Skywave, SWLing Post reader, William Pietschman (W8LV) comments:

I find that the Skywave is so stable on the air band, I can use it to decode ACARS with the Android App!

Listened to WBCQ, and Arnie Coro’s show last night from Havana along with some Jazz music.

It pulled FM stations out of the air like nothing else, meaning the weaker ones here in my rural Ohio location. And I could pick up three NOAA broadcasts, two very strong, one scratchy…. Since the NOAA system is of course designed to let you pick up one station in whatever particular area of the county you live in, I consider this excellent!

With the AM I pulled in Canadians, Boston , stations in IOWA and KFI. I also note it’s very directional on AM… I could null out WTVN and pick up Texas with no problem. I have owned and do own lots of shortwave radios, and I MUST say, this is one hell of a good set!

It’s going into my Winter zip-up jacket pocket so it will always be handy for the DX Season, and I also notice that the headphones are VERY good, and have a long enough cord so it’s not pulling at my ears like some sort of damned harness… I HATE short earphone cords!

(And while I am on the subject of ear phones, and while I haven’t been zapped in the ear with static this year yet by dry air causing that annoying problem, I wonder how these earphones are going to do in that regard… the Sony’s are unbearable in Winter! Ouch! I wonder if anyone else out there has this problem besides me, and has found a solution?)

First of all, thank you for making me aware of the ACARS app and that you can successfully use it with the CC Skywave. I will add the ACARS app to my growing list of HamRadio/SWL applications and also try it myself!

Your experience with the CC Skywave is very similar to mine. It is a fabulous portable receiver. If it only had SSB and sync detection, it would be the ultimate compact portable. The CC Skywave is an everyday carry (EDC) radio for me–either it, or the Sony ICF-SW100, accompany me everywhere in my Timbuk2 messenger bag.

Regarding static discharge from headphones, I don’t think I’ve ever had this happen to me; sounds annoying, though! I suppose walking in dry winter conditions with a thick winter jacket could increase chances of discharge. Perhaps the in-ear design of the included CC earbuds–with silicon earpieces–will minimize and insulate you from this problem? Let us know!

Thank you for your assessment of the CC Skywave, William!

Many thanks to SWLing Post contributor, Dan Robinson, who shares a radio comparison he initially posted in the excellent Extreme Shortwave Listening Facebook group. Dan writes:

When the Sangean ATS-909X was first released a few years ago, I decided that I would hold off obtaining one to let whatever bugs there might be in production get worked out.

I have always been impressed by the design of the 909X, but was cautious when it came to the question of overall sensitivity. I once owned the 909, had it modified by Radio Labs, but that seemed not to do much — the 909, in my view, suffered too much from the well-known deafness issue when using the whip antenna.

Over the years, I used and still own many of the classic portables. This includes the SONY 7600GR, Grundig SAT 500/700, 2010, E-1, SONY SW100/SW07, SONY SW-55, and the radio I consider to be at or near the top of the small portable heap, the Pan RF-B65. But a couple of weeks ago, I broke down and bid for a new in box Sangean 909X. It’s the black version, and arrived a couple of days ago.

I remain impressed by the 909X’s design — beautiful radio, wonderful large LCD and backlight, excellent filtering, along with a feature we used to see in the SONY’s — adjustable/variable attenuation. But I wondered how the 909X would stack up against two of my favorites, the SW-07 and RF-B65. I was crossing my fingers — but alas, initial results are not encouraging.

While the radio initially on its own seems to be quite sensitive, I lined it up next to the SW-07 and RF-B65 and did a comparison. Now, first I must note that propagation continues to be in the dumpster and I conducted this test in late afternoon.

All three receivers were tuned to Cuba on 11,760 khz — they were located next to one another on a table in the top level of my home here in Maryland. The results are seen in the video below.

You can hear how much more clearly the SW-07 and especially the RF-B65 handle a signal. With the Panasonic, stations just pop. Same with the SW-07.

Disappointingly, as you can hear, stations on the 909X appear to be buried in noise. It’s quite extraordinary — I was very surprised by this comparison and intend to perform additional side-by-side tests in different areas of my home, which does suffer from high noise levels likely produced by electric lines and a transformer outside (which is why a run a Wellbrook on my main radio stack downstairs). But it is notable that the 909X appears to struggle so, while the old classic portables SW-07 and B65 excel. Interested in the views of others . . .

Dan, this is very similar to my experience with the Sangean ATS-909X.

Like you, I absolutely love the design of the 909X–the large display, tuning wheel, front-facing speaker, ergonomics–but was pretty disappointed when I pitted it against three other (less expensive) portables on the shortwave bands.

I know the 909X performs much better when connected to an external antenna. I’ve also learned that fresh batteries are a must as the 909X’s sensitivity is directly related to supplying optimal voltage. I know, though, that you had fresh batteries in your 909X, Dan.

Again, many thanks for sharing your comparison.

Last night, I noticed an untested American Electrola DXC-100 shortwave/AM/FM radio listed on eBay: it had a BuyItNow price of $49 shipped.

The seller (who has an excellent feedback history) disclosed that the power supply was missing, thus the receiver couldn’t be tested.

As you can see from the photos, it’s in great cosmetic shape.

I’ll admit it: I purchased the DXC-100 in a moment of weakness this morning. I don’t expect it to be much of a performer, but it is a relatively rare 1990s receiver that was built in Pittsburgh, PA. I believe only 2,000 units were produced. I have a weakness for odd-ball receivers.

I’m willing to bet the DXC-100 is functional, though the backup battery may need to be replaced.

Does anyone have a schematic or owner’s manual for the DXC-100? I will have to find or build a suitable 9V power supply but need to determine the proper polarity first.

I’ll do a short review of the DXC-100 if I’m able to get it on the air.

Many thanks to Scott (AK5SD) who shares the following photos and bill of materials for his custom Elecraft KX3 go-box:

and 3.5mm (PH-44-468 for stereo, PH-44-470 for 4-conductor) audio cables with right
angle plugs and just cut them to use for the signal lines going to the KX3. I did the same
thing for the 2.5mm (PH-TC250) and 2.1mm (PH-TC210) power cables. A couple of
caveats are in order. The Phone, Key, and ACC1 interconnects require low profile
right angle connectors. The cables I listed above won’t work. Vetco part number
VUPN10338 will work. The power cables I’ve listed above use 24 gauge wire. This
is a little light, but the runs are small so I think it is OK. You can use higher gauge
cables if you can find a source.

This is optional if you want a built-in sound card interface for a waterfall display using iSDR. Make sure to eliminate the holes in the upper left corner of the panel if you are not installing. You will also need 2.5mm x 10mm screws to mount this to the bottom of the panel (see below).

bhi Compact In-Line Noise Eliminating Module (OPTIONAL)

In my opinion, the KX3’s noise reduction is totally ineffective for SSB communications. This external noise reducing DSP is one solution, albeit an expensive one, to that problem. It is only for SSB, not CW or digital modes. It is also available from GAP Antenna Products.

Scott: you have done a beautiful job here and have spared no expense to make a wonderfully-engineered and rugged go-box. No doubt, you’re ready to take your KX3 to the field and enjoy world-class performance on a moment’s notice. 

Though I’ve never used them personally, I’ve noticed others who have taken advantage of the Front Panel Express engraving service–certainly makes for a polished and professional front panel.

Again, many thanks for not only sharing your photos, but also your bill of materials which will make it much easier for others to draw inspiration from your design!

Speaking of designs, when I looked up Scott on QRZ.com, I noticed that he also sports a QSL card (above) designed by my good friend, Jeff Murray (K1NSS). Obviously, Scott is a man with good taste!

On Thursday I attended an event at the Pisgah Astronomical Research Institute (PARI)–location of the 2015 SWLing Post DXPedition.

During a break, I had a couple of free hours, so I reached in my messenger bag and pulled out the Sony ICF-SW100: a radio that has quickly surpassed all others as my favorite EDC (everyday carry) radio. It has so many useful features in such a small package!

Radio astronomy observatories are ideal locations for impromptu shortwave radio listening as there is little to no radio interference/noise present.

PARI’s “Building 1” and the 26 West (left) and 26 East (right) radio telescopes.

While the weather on Thursday was gorgeous, HF band conditions were…well…miserable. There was very little to hear other than China Radio International, Radio Havana Cuba and a few other blow torch broadcasters.

Still, time signal station WWV was on my mind since I had just purchased Myke’s new edition of At The Tone and have been reading your excellent comments with early memories of listening to WWV and WWVH.

I tuned to 15 MHz and, of course, there was reliable WWV in Fort Collins, Colorado on frequency. Though WWV’s signal was relatively strong (despite the conditions) I turned on the SW100’s sync detector because fading (QSB) was pronounced at times.

Here’s a short video of the ICF-SW100 on a picnic table in the middle of the PARI campus. That’s PARI’s 26 (meter) West telescope in the background:

You got me hooked on those little credit card sized radio kits from an eBay seller so much that I have bought a few more of his kits. I’ve found them to be so much fun, that I have started looking elsewhere for other tiny radios.

I came across this the other day and while it is not a kit, I was wondering if you or your readers had ever tried them and if so, what your opinions are: http://jdradio.weebly.com/index.html

I know it is likely more novelty than performance, but the prices seem ridiculously low for individual buyers.

Also seen here: http://www.centretradegroup.com/Radio.php

I’m not familiar with the earpiece radios in your links. I have read through those sites, though–unfortunately, as I’m sure Vance noted, they lack any in-depth information.

I did a quick Google search and can see that these radios (both the FM and AM versions) have been around for many years–some references go back to 1999.

I imagine the earpiece radio uses the same auto-tuner that became quite popular in the late 90s. Simply press a button and the receiver auto-tunes to the next strong station: no memories and not manual tuning. Indeed, I used to attend trade shows in Europe in the late 90s and several vendors actually gave away branded novelty radios (in a variety of shapes) with a similar tuner.

Readers: Ever use one of these earpiece radios? Please comment!

Trip Down Shortwave Memory Lane via Vintage RS Catalogs

-Mario Filippi (N2HUN)

Attached is a wonderful website containing archived Radio Shack catalogs and sales flyers going back to 1939, surely of interest to SWLs, hams, and other electronics hobbyists. Most of us have fond memories growing up and visiting our local Radio Shack when it was the place to go for ham, shortwave, and scanner radios. My hometown Radio Shack was located on North Avenue in New Rochelle, NY and I purchased an electric guitar (could not afford a Fender) from them in the late 60’s which had three pickups and included a case for $29.95!

Radio Shack Catalogs

You see, back then Radio Shack had a much more diversified line of products, including musical instruments, power tools and even scientific stuff like microscopes and slide rules. These archived catalogs are a treasure trove of information not only from a historical perspective, but for anyone who is interested or who is contemplating purchasing vintage equipment such as shortwave radios, because you can look up the original sales info in the RS catalog which contains the original price, photo, description, and accessories available at that time.

For example, last year I purchased a “tech special” Realistic TRC-450 AM/SSB CB radio on Ebay that needed LED repair, so I looked up the original sales ad and got the price, photo (this helps to see original condition), and product description. Below is a picture of my restored Realistic which originally sold in 1980 for $269.95!

The classic Realistic TRC-450 AM/SSB CB radio. (Photo: Mario Filippi)

Nowadays most people don’t realize how expensive electronics were a few decades ago. A comparable new AM/SSB CB radio sells for about half that price nowadays!

Lastly, as one progresses chronologically through the catalogs, you can see technology (and even fashion) trends – the large 8 track tape decks of the 60’s and 70’s progressed to smaller cassette players of the 80’s and 90’s, then DVD/CD players made their entrance, ultimately giving way to higher tech forms of entertainment such as satellite radio and Internet-based entertainment. Well I hope you enjoy this totally entertaining and informative website and I thank the individual who took the time and effort to preserve for perpetuity these priceless annual time capsules for everyone to enjoy.

Mario, many thanks for this trip down memory lane!

As you state, these catalogs are actually an excellent reference source when trying to determine pricing and features of RS radios found on the used market.

I think they’re also so much fun to flip through as they’re chock-full of nostalgic value. When I was a kid, I could care less about toy store catalogs–the RadioShack catalog was my toy store!

Indeed, when I open the online catalog copies at Radio Shack Catalogs, I can almost smell the ink on the pages! Am I the only one?

SWLing Post contributor, James Patterson, has recently restored a Sony ICF-5800H. James sent me a few photos and I decided to post them here.

I absolutely love the design of Japanese analog radios from this era. They have signal meters, large backlit dials, carry straps, and proper large controls–buttons, switches and knobs–that can even be operated when wearing gloves in the winter.

Great receiver you have there, James!

SWLing Post reader, Pat, is an avid cyclist and is seeking a radio for his next cross-continent adventure. There are a limited number of products on the market that meet Pat’s requirements, so I thought posting his inquiry might bring a few options out of the woodwork. Check out Pat’s requirements and please comment if you have a suggestion!

I’m a professional ski coach from Colorado. When I’m not on skis, I like to get on my bicycle and go explore the world. I’ve ridden across the USA a few times, covering all 48 states in the Continental US. A couple of years ago I got my 49th state when I rode from Alaska back home to Colorado.

Next year I plan to ride to Argentina, a journey of 12,000 miles over six months.

One of the things that keeps me sane is to have a radio strapped to the handlebars of my bike. I used to have a cheap AM/FM transistor, but have slowly improved the choice of radios on each trip.

During my Alaska ride I used a Degen DE1123, which was a great item. Not a great radio, but having an mp3 player built in made a world of difference. There were some mighty long distances without radio signal, so having the mp3 was great. But like I said, the 1123 wasn’t the most user-friendly item. Plus, it ate up AA batteries, which were pricey in the Yukon. So I upgraded to the Degen DE1125. Certainly an improvement, but still some things that could be improved. [See photo above.]

For my Argentina trip I want to have something really good; something that works well and will hopefully last six months. Also, I really like the idea of having a radio with a mini SD slot. I’ll have to download a lot of music and podcasts to keep me happy.

Someone suggested the Melson S8. I purchased one and it is a great unit, but way too big to fit on the handlebars.

You obviously have experience with many different portables and I was wondering if you could give me your suggestions. Maybe something from Degen, ShouYu, Tecsun?

Things that are important:

• Ease of use (I’ll be using the controls while pedaling)
• Weight (smaller and lighter is better)
• Durability
• Mini SD capability
• Radio reception
• AM, FM and SW capability
• Li-ion batteries

Not overly important:

• Ability to scroll through songs/find songs
• Sound quality (I’ll have wind in my ears anyway)

Things that are not important:

• Recording ability (I don’t foresee recording anything along the way)
• Looks
• Cost (I don’t want to spend $150 on a CC Crane, as the radio may get broken or stolen, but I’m willing to spend some money on a quality product if available).

[…]I’d love to select the best option for this silly ride I’m taking next summer and will happily take any advice.

A cycling trip to Argentina? Nothing silly about that, Pat! What an adventure!

Shortwave radios with MicroSD slots are somewhat limited in numbers, but more and more models have appeared on the market in the past few years.

Readers: can you help Pat with some suggestions/options?  Please comment!

When I discovered that Degen had recently refreshed the receiver design of the DE1103, I was intrigued, to say the least. The original DE1103 sported some serious performance for a sub-$100 receiver.

The 2015 model of the Degen DE1103 implements a DSP chip (the Silicon Labs Si4735-D60).

Yet I was on the fence about purchasing the new DE1103. Why? In truth, I never fell in love with the original DE1103. While I appreciated the 1103’s unique analog-style digital display, I never got used to its quirky ergonomics. Degen had quality control issues, too: I had to return two faulty units before getting one that worked as advertised (incidentally, I had a similar problem with the Kaito KA1102).

Then last week, SWLing Post reader, Ron, contacted me. He had purchased the new DE1103 from Hong Kong-based eBay vendor Bigbargainonline.

Ron kindly provided the SWLing Post with his impressions of the DE1103, as follows:

Performance is roughly on a par with the earlier dual conversion version. This one is just as hot, but no hotter.

If you were thinking a GP5 on a bigger ferrite bar, yes…and no.

There is one major gripe…[this unit] will not remember frequencies set with the BFO on, like the earlier dual-conversion version did. Instead you have to turn the BFO on for each memory frequency [for which you] need it.

One thing [I] noticed right off was the almost complete lack of AGC “pumping” on CW and SSB that all earlier versions had (yay!) but this plus comes at the cost of having the BFO “remembered” in memory.

Zero-beating (or centering) the BFO to null on WWV and local AM stations to check alignment was…strange. At null beat the BFO seems to quit for a second. It is fine
either side of zero beat, however.

This is doubtless due to Tecsun’s adapting the Silicon Labs IC to a full range BFO like this. Recall the same IC in the GP5 features Upper and Lower selection on CW/SSB.

This 1103 DSP version also has the GP5’s slight tuning mute, not a problem.

But for ease of operation in CW/SSB mode, the GP5 is [much] better IMO.

Ron also notes that he wasn’t pleased with the DE1103’s longwave performance and didn’t feel the mediumwave and shortwave reception was an improvement on the original DE1103.

He decided that he would sell this DE1103 and gave me first dibs, so I bit the bullet. I was eager to compare the new DE1103 with some of the other DSP-based portables in my collection. Ron dispatched the DE1103 immediately–it arrived a few days ago, but I didn’t have a chance to test it until yesterday.

I took the Degen DE1103 outside, sat it on the tailgate of my truck and put it on the air…

I tuned around the mediumwave band and picked up all of the local benchmark stations. Same with FM. So far, this tuning confirmed Ron’s assessment of the DE1103: it didn’t surpass the original.

But the shortwave bands were a different story.

As I tuned around the HF bands, the DE1103 seemed to receive quite a lot signals.  But in most instances, I could hear local AM broadcasters bleeding in, as well. Indeed, imaging was prevalent across the shortwave bands–the receiver was obviously being overwhelmed by a local broadcaster.  Unfortunate.

Could strong interference account for this? While there are local AM broadcasters around, they’re not exactly “blow-torch” stations. Indeed, I’ve never had overloading issues with other shortwave portables I’ve used in the same location–not even with my Kaito WRX911!

Imaging was prevalent on the DE1103 when it was tuned to pretty much any audible shortwave broadcaster.

Here’s a video of the Degen DE1103 tuned to the Voice of Greece on 9,420 kHz:

What you’re hearing in the audio is a local broadcaster bleeding in. Note that when I tune off-frequency, no imaging is heard.

Wondering if something had changed locally–and just to be fair–I pulled out my Sony ICF-SW100 and sat it next to the DE1103. The Sony had no issues.

This time, I tuned to WWV on the 19 meter band and compared the two receivers:

As Dan Robinson expresses it, the ICF-SW100 “wipes the floor” with the DE1103. There’s no hint of overloading in the SW100.

My buddy, Ron, is clearly a keen radio reviewer; obviously he didn’t hear overloading on the shortwave bands where he tested the rig, else he would certainly have mentioned it. The location where I tested the DE1103 does have some local broadcasters in the area, but no clear channel or high-power stations; in short, there’s no likely interference within a ten-mile radius to account for this debilitating performance problem.

Too bad…!

Obviously, the new DSP version of the Degen DE1103 is especially prone to imaging on the shortwave bands. In fact, it’s the only receiver I’ve ever tested that has overloading issues at this testing location (where I tested the original Degen DE1103, by the way).

My assessment? Avoid the new Degen DE1103.

A much better receiver with SSB for roughly the same price would be the venerable Tecsun PL-600 ($89.99 at Amazon and $89.95 at Universal Radio). If SSB reception isn’t necessary, you might also consider the CC Skywave or the very affordable Tecsun PL-310ET.

Many thanks to SWLing Post contributor, James Patterson, who writes:

Has anyone ever thought of changing the Tuning knob on the PL-660?

Putting a larger knob on it makes for much easier turning instead of the very small fiddly knob Tecsun supply.

Finding the right plastic knob maybe a problem, needing to insert it over the tuner cam. But modifying another knob off something else is what I did.

Tricks of the trade!!

That looks like a very simple and effective mod, making the 660 more tuner-friendly for you! Thank you for sharing, James!

Many thanks to SWLing Post contributor, Jeff McMahon (at the Herculodge), who writes:

I upgraded my Sangean U3 with a male to female iMBAPrice 6 foot stereo audio extension cable 3.5mm, which I plugged into the U3’s auxiliary port.

The U3’s small stub of an FM antenna really needed some extra oomph. Now my U3 is picking up all my favorite stations, including the problematic KPCC 89.3 in Pasadena.

AM is as great as always. The sound is crystal clear on AM and FM. If this radio weren’t so big, I’d buy two more for the kitchen and my bedroom, but will have to be content to have one for my gym/office radio.

Thanks, Jeff! I might have to consider the Sangean U3–I hope a reader will let me know if one goes on sale.

Like Jeff, having a radio that not only performs admirably, but that can also withstand the attention of my kids, may be a great investment over the long-term! I’m glad such a simple addition to the U3 means that you can now hear your favorite Fm station, Jeff!

Now if Sangean only made a shortwave version of the U3–!

In response to our Mega Review, Danny Bower comments:

Fantastic review and whilst I know the article is an older one people will still read it when looking at a portable SW radio.

With this in mind I would like to make the following comment about the PL660. You say it is bulletproof and boy is it! Mine has been dropped, kicked and overwise abused and it’s still going strong.

Most remarkably it was knocked into a bucket of water, plugged in and powered up and was there for a good couple of hours fully submerged before I realised.

It wasn’t long good for a week or two but after 3 or 4 weeks I have it one last try before binning it and hey presto it came back to life! Ok the volume pot is now a bit scratchy but other than that it’s working just fine.

Want a radio that will take the general abuse of travelling – this is it…

Wow!  Thanks for your comment, Danny! Most impressive that your PL-660 went diving that long and lived to tell the tale. Thanks for sharing!

This morning, I checked a few retailers for “Cyber Monday” deals and took notes along the way. Some of the best finds came from Blinq, a retailer I’ve purchased from a number of times.

Updates

Ron notes that “CountyComm has extended their ‘buy a GP5, get the 17 buck custom
carry case for free’ offer through today, November 30th.”

This article originally appeared in the November 2015 issue of The Spectrum Monitor magazine:

Despite the often-expressed view that shortwave may be on the decline, if one were to look at this year’s shortwave technology alone, the truth would seem to be anything but. Remarkably, 2015 has been a great year for the shortwave radio listener, as several models of portables, tabletops, and SDRs have been either introduced or improved.

The following is a basic, easy-to-follow buyer’s guide to some of the best receivers on the market currently. This guide is, by no means, comprehensive; rather, it’s a selection of rigs I have tested, some of which I now own. It builds on the guide I published in the November 2014 issue of TSM, and highlights innovations since that issue, while still acknowledging the contributions of previous models.

Compact/Travel portables

If your budget is tight, or if you’re looking for a radio that could easily slip into your glove compartment, backpack, carry-on, or even jacket pocket, you need to consider a compact shortwave radio.

Typically, there is a performance compromise with compact radios: they don’t always have the sensitivity of their more expensive cousins; they have a more limited frequency range; and they don’t detect single-sideband signals. Nonetheless, the ones listed here are fine performers for their size and price. Entries are listed in alphabetical order.

The Eton Traveller III

Eton Traveller III

Eton has once again refreshed the design of its popular “Traveller” series of compact receivers: their latest is the third edition, the Eton Traveller III. I’ve owned the past two versions of the Traveller, and having learned to appreciate these, was eager to get my hands on the newest Traveller III. As the name implies, this is a great little radio for the international traveler; it not only has shortwave, AM and FM bands, but it also has a world clock that can easily be switched from the front panel, a useful alarm function, and great built-in speaker. New to the Traveller III is FM RDS: a great way to capture FM station identification when visiting a new city. The key lock is prominent on the front panel and the included padded nylon case is one of the most rugged I’ve seen in years. Performance is what I’ve come to expect from the Traveller series: superb AM (mediumwave) reception, great FM reception, and capable shortwave reception. It lacks the multiple bandwidths found in other similar DSP radios, but my impression is that the default bandwidths are adequate for multi-band listening.

The Eton Traveller III is available from Universal Radio, Amazon.com and more outlets via Eton. Pricing ranges from is $55-60 US.

The C.Crane CC Skywave

CC Skywave

Only a couple of weeks before the Christmas holiday of 2014, C. Crane introduced a compact portable that truly impressed me: the CC Skywave. The Skywave is as compact as any other ultralight radio, but adds a host of features that has made it an invaluable radio for my one-bag air travels. The CC Skywave covers the following bands: Shortwave, AM, FM, Weather, and Aviation. It’s a comprehensive toolbox of frequency bands and listening modes which only lacks, sadly, SSB.

Ergonomics are excellent for such a small portable. It’s easy to use, as well: I only needed to reference the well-written manual for a few functions. I find the CC Skywave to be very sensitive on shortwave and mediumwave, rivaling radios that cost much more.

One negative I’ve learned through readers of the SWLing Post is that the first production run of the CC Skywave was prone to overload in the presence of strong local broadcast stations. C.Crane have confirmed that this has been addressed in the latest CC Skywave production run and is no longer an issue. To insure you’re receiving a unit from the latest production run, consider purchasing directly through CCrane.

The CC Skywave is sold by Universal Radio, Amazon.com and directly by C.Crane. Price is $89 US.

The CountyComm GP5/SSB

CountyComm GP5/SSB (Tecsun PL-365)

CountyComm––a retail distributor of products created primarily for use by the US government––introduced a new shortwave portable late in 2014: the GP5/SSB. The GP5/SSB came about as a result of a large order CountyComm received from a US government department for an “inexpensive, small portable, AM/FM/SW radio with SSB” for emergency supply caches and diplomatic posts. Like its predecessor, the GP5/DSP, the GP5/SSB has a vertical form factor, much like a handy-talky, and a detachable/rotatable ferrite bar antenna that greatly improves AM/mediumwave reception. The GP5 series is limited by a small internal speaker that sounds somewhat tinny; it also lacks a direct entry keypad. Still, with a pair of headphones and some careful memory allocation, the GP5 is a pleasure to use.

If you’re looking for an ultra-portable radio with SSB, then the GP5/SSB is a very good choice. (It may, in fact, be the only ultra-portable SSB choice currently on the market). While the SSB performance can’t compare with larger, pricier receivers, or ham radio transceivers, it’s very good for $80 US. If you’re looking for an emergency communications receiver––something to stash in your vehicle, emergency kit, or bug-out bag––the CountyComm GP5/SSB is a great choice and value. Indeed, that’s who the GP5/SSB was designed for, and why this rig has excellent frequency coverage in all modes, with good sensitivity/selectivity and designed for portable, one-handed operation. In fact, CountyComm has even designed and manufactured (and in the USA!) a robust, protective 1000-Denier case for the GP5/SSB. This case makes it very easy to strap the GP5/SSB to your belt or backpack securely.

The CountyComm GP5/SSB is available from Universal Radio and directly from CountyComm.

The Sangean ATS-405

Sangean ATS-405

I was surprised this year when Sangean introduced its latest compact/travel receiver, the ATS-405. I had heard rumors that Sangean may have been leaving the shortwave radio scene, so was pleased to learn that Sangean was not only still invested in the hobby, but innovating. Indeed, the ATS-405 has features that have not yet been included on small DSP-powered portables: specifically, the ability to control squelch, tuning mute, and soft mute.

The ‘405 is a decent little radio with a great deal of functionality and features for a rig in its price class. But overall, its performance seems rather mediocre. If you primarily listen to FM, you’ll be pleased. If you’re a mediumwave listener, you’ll be pleased only if you don’t mind the 800/1600 kHz DSP birdies which plagued both of my review units. If you’re primarily a shortwave listener, you’ll need to carry a clip-on wire antenna to bring the sensitivity up to the level of similarly-priced receivers. I also found performance variations between my two review units; an indication that quality control is somewhat inconsistent at the factory.

The Sangean ATS-405 is available via Universal Radio and Amazon.com. Price is $89 US.

Other compact/travel radios

In the 2014 Buyer’s Guide we included several other compact travel radios worth considering: The [original] Kaito KA1103/Degen DE1103, Tecsun PL-310ET, and the Tecsun PL-380 to name a few.

Full-Featured Portables

In the portables market, I believe you get the most value and quality in the $90-250 price class. Most beginners and seasoned SWLs prefer a radio that includes everything necessary to get on the air immediately; all of these radios provide just that. Straight out of the box, you’ll have everything you need to listen to shortwave bands. All of these recommended radios are designed to pick up major shortwave broadcasters with ease, and offer the following features: good frequency coverage; circuitry that helps in the detection of weaker stations; and with a few notable exceptions, the ability to receive single-sideband.

The Tecsun PL-680

Tecsun PL-680

The latest Tecsun full-featured portable––the PL-680––appeared on the market in February this year. Cosmetically, the receiver is nearly identical to the Tecsun PL-600, but with the added features of the Tecsun PL-660. Indeed, in terms of features and comparing them with that of the venerable PL-660, there are no obvious additions on the PL-680. The PL-680 has been improved, however, in its shortwave reception. The PL-680 is both slightly more sensitive and has a more stable AGC (Automatic Gain Control) than the PL-660. If you are primarily a shortwave radio listener and wish to have one of the best sub-$200 receivers currently on the market, the PL-680 may be the rig for you.

On the other hand, if you are primarily a mediumwave DXer and already own the PL-660, you will likely want to pass on the PL-680. The PL-680’s mediumwave reception is simply not as good as that of the PL-660. The PL-660 is both more sensitive and has a lower noise floor on mediumwave.

Note that since its introduction, inventory of the PL-680 has fluctuated; the primary retailer is Anon-Co in Hong Kong and on eBay. Price is $95 US (plus shipping from China).

The Eton Satellit

Eton Satellit

Last year, Eton released the Satellit: a new full-featured portable, essentially replacing the venerable Grundig G3, but carrying the name of the flagship Grundig Satellit series.

The Satellit has many of the same functions as the Grundig G3, and has a near-identical form-factor, but sports a new amber backlit display, multiple bandwidths, and a double-jointed telescopic antenna. The Satellit performs admirably on the AM/mediumwave bands, quite well on the shortwave band but, most notably, performs brilliantly on FM. The audio fidelity from the built-in speaker is quite robust; indeed, it’s among the best in its class. The key layout and ergonomics are similar to the Grundig G3 and G5; meaning, the radio is quite simple to use. One negative is that the Satellit mutes between frequencies while tuning, however, this is minimal in the most recently-updated production runs. I’m very pleased that all of the new Eton radios lack the tactile rubber coating found on some previous models, for while the coating works excellently to improve one’s grip on the radio, over time it can become sticky to the touch (if you find this to be a problem, here are several techniques to clean the sticky residue: http://bit.ly/1KQN8TX).

At time of print, the Satellit is generally available for about $180-190 from a variety of retailers, including Universal Radio and Amazon.com.

Other full-featured portables

In the 2014 Buyer’s Guide, we included several other full-featured radios that are still certainly worth considering: The C. Crane CCRadio-SW, Sangean ATS-909X, Sony ICF-SW7600GR, Tecsun PL-600, Tecsun PL-660, and the Tecsun PL-880.

Hybrid Stand-Alone SDR/Tabletops

While tabletop receivers have started to decline with the advent of SDRs, there are many listeners who still prefer a simple, dedicated, stand-alone high-performance receiver with a good tuning knob and clear display, which is to say, a tabletop receiver. Tabletops are designed to perform best with a resonant external antenna.

The Elad FDM-DUOr

Elad FDM-DUOr

If you’ve been thinking of purchasing an SDR, but really want a traditional front-panel tabletop receiver, the Elad FDM-DUOr may be for you. I’ve included the FDM-DUOr under the tabletop heading because it is, in fact, a tabletop receiver, with the features of a tabletop such as a front panel, knobs, display, and capability to operate independent of a PC. However, if you choose to hook it to a PC, you unleash a full-fledged SDR and a wide array of features. The FDM-DUOr is built on the same receiver and software as the FDM-S2, one of my favorite sub $1000 SDRs. The FDM-DUOr also sports 10 selectable and customizable filter preselectors and an internal switch box for use with an external transceiver.

At time of print, Elad is seeking FCC approval for the FDM-DUOr in order to distribute these units in the USA. The FDM-DUOr is currently available in Europe via the Elad online store: Price is 899.00 €.

The CommRadio CR-1a

CommRadio CR1-a

US-based manufacturer CommRadio introduced the CR-1 in 2013––an amazingly rugged, portable receiver, and essentially a small tabletop SDR. I’ve used mine in travels and at home; the built-in rechargeable battery will power it for hours, it’s built to a mil-spec standard, and it performs like a champ.

In 2014, CommRadio increased the SDR potential of the CR-1 by updating with a new model: the CR-1a. In 2015, CommRadio continued to add features to the CR-1a through firmware and software upgrades, such as a new Spectrum Viewer SDR application, and 3D-Waterfall for Windows PCs.

CommRadio CR-1a owners only need to update their firmware and download software to use the new feature. The CR-1a is priced at $599.95 US, shipped, and includes a battery through Universal Radio––good value for a quality piece of kit. CommRadio also sells the CR-1a directly through their website.

Other tabletops

In the 2014 Buyer’s Guide, we included several other tabletop radios, including the Alinco DX-R8T and the Icom IC-R75.

SDRs/IF Receivers

If you’re searching for maximum performance for the price, software-defined radios (SDRs) and IF receivers are hard to beat. These small “black box” radios require a computer to unlock performance, none are stand-alone. But while I was never a fan of combining my PC with radio listening, once I starting using an SDR, I never turned back. Now, 90% of the time that I’m on the air, it’s with an SDR. The ease of doing so is incomparable, and the functionality simply incredible.

The Elad FDM-S2

Elad FDM-S2 and the new SPF-08 preselector

If you read the Elad FDM-S2 review in the November 2014 issue of TSM you’ll know that this little SDR packs a powerful punch for the price. FDM-S2 performance is uncompromising, comparing favorably to receivers $300-400 more in price. The S2 also provides native DRM decoding; it’s a fine DRM receiver.

Users who live in the vicinity of high-powered AM stations will be pleased to know that Elad has developed an outboard preselector box that pairs with the FDM-S2––the new SPF-08, which covers the amateur radio bands. Elad already has a broadcast band version of the SPF-8 in development. The SPF-08 enclosure is the same size as that of the FDM-S2 and couples with it directly via a port on the back of both units.

Both the Elad FDM-S2 and SPF-08 are available via Elad’s online store: http://ecom.eladit.com/

The SDRplay RSP

SDRplay RSP

The SDRplay RSP was one of the most pleasant surprises I encountered in the world of software defined receivers this year. I published a review of the RSP in the May 2015 issue of TSM; in short, I was amazed at the performance of this $149 SDR. While it doesn’t have its own proprietary SDR application, it is compatible with some of the most popular free applications on the market: SDR Console, SDR Sharp, and HDSDR to name a few. SDRplay developers are even testing a Raspberry Pi application for the RSP.

Since the time of my review, SDRplay has updated the RSP to include gapless coverage from 100 kHz to 2 GHz––talk about wideband coverage!

If you have been hesitant to invest in a benchmark SDR, or simply want to explore the world of SDRs on a small budget, the SDRplay RSP is a no-brainer. Without a doubt, it packs a lot of performance in a tiny, affordable package. The SDRplay user community is also very active and routinely pushes the boundaries of this little receiver.

The SDRplay RSP is available at SDRplay.com and, in the US, at Ham Radio Outlet.

The RFspace Cloud-IQ

RFSpace CloudIQ

The Cloud-IQ is the latest software-defined receiver from the US-based company RFSPACE. The Cloud-IQ offers two modes of operation:

• the “IQ mode,” which provides 24-bit IQ streaming to your PC over an ethernet cable (much like the RFSpace NetSDR).
• the stand-alone “cloud mode,” which includes a built-in internet server. In cloud mode, according to RFSpace, “the receiver performs the tuning and demodulation of signals and transmits the demodulated information back to a PC, OS-X, Linux, or Android client anywhere in the world.”

RFSpace is essentially one of the first SDR manufacturers to include built-in SDR streaming functionality, something that has been somewhat complicated to implement in other SDRs.

The price point is also favorable at $629.95 through Ham Radio Outlet, Amazon, Astroradio and ML&S. Availability has been quite limited this year, but more production runs are planned for the near future. I plan to review the RFSpace CloudIQ in late 2015 or early 2016, as soon as a unit becomes available.

Other SDR/IF receivers

In the 2014 Buyer’s Guide we included several other SDRs and IF receivers worth considering, including the Bonito RadioJet IF-Receiver 1102S, Microtelecom Perseus, and the WinRadio Excalibur. Additionally, note that the affordable Airspy SDR will soon have a new converter to cover HF down to 1kHz–look for a review in 2016.
